If a stress echocardiogram shows the heart is structurally sound when done five years ago does it need to be repeated? In other words is it necessary to repeat the procedure if it was done for checking PVC's etc. I have been having some tachycardia , related I think to panic attacks as well as excercise. Do I need to be reevaluated again?

If you have new symptoms then it would seem appropriate to repeat the test and I don't think a five year interval is to short to repeat the test. Some of the symptoms are exercise related so this should be a good test for you.
